On co-orbital quasi-periodic motion in the three-body problem
(2019-01-01)
Article
Accés obertWithin the framework of the planar three-body problem we establish the existence of quasi-periodic motions and KAM $4$-tori related to the co-orbital motion of two small moons about a large planet where the moons move in ... -
On the mechanisms of natural transport in the solar system
(2010)
Text en actes de congrés
Accés obertSome minor bodies in the solar system (i.e., comets, asteroids and planetary ejecta) are capable of performing transfers from their original location to very distant places, provided they possess sufficiently large ... -
On the relationship between the weak stability boundary region of the earth and the low-energy transfers to the moon
(2009)
Text en actes de congrés
Accés obertThe term Weak Stability Boundary (WSB) is related to a region of stable motion around the second primary of a circular restricted three-body problem (CR3BP). Previous work on this subject has shown that, at a given energy ... -
